Its cold and I need some blower motor help

So I'm driving down the street and the blower just kicks off. It was on high and it just died...but here is the weird part. The lower 3 settings still work fine. Its just when I put the switch on high that the motor completely dies. If a fuse blew, don't you think that all the settings would be dead? What controls just the high setting besides the switch. BTW the switch was replaced with a new one from LMC last summer. Any ideas? Thanks

Thanks for the help guys. This afternoon I was able to get the blower back to normal...hopefully it will stay fixed. I took the resistor out and sprayed it down with some contact cleaner...jiggled some wires and pushed down on all of the connectors. Thats it and it fixed it. Probably just a bad contact somewhere, but if it happens again I'm going to replace the relay first.

Look for a square metal can (about 2x2x1") on the side of the A/C box in the engine compartment. It's got a 12 or 14 gage orange wire going to it, should be easy to spot. The relay cover comes off, and if the contacts aren't burned and pitted, you can take a business card and clean the plated contacts, instead of replacing it. HTH

Sounds like your going to need a new motor ($18.95@Autozone). That was one of the symptoms mine had about 6 months ago. Mine wouldn't work on high and then started making this weird whining noise kinda like when your water boils in your ratiator after a thermastat stick. It finally puked last week. Very easy install.
